Yeah, I like to collect old CRT's (small ones, like from portable TV's, camcorder viewfinders, etc) so I use this sig gen to test and align them.

I want the RGB output option so I can find and test direct RGB input into the colour CRT's I have, then my plan is to use one of those ebay HDMI or VGA to RGB converter boxes to convert old mini colour CRTs to HDMI/VGA/etc.Will make for nice raspi screens for retropi or custom retro monitors for vintage PC's.

Makes sense. Thanks, guys. I only have two CRT TV's left. When they need alignment, I'll know what to get.

The probes are for my new, unlocked SDS1104X-E.I know the hotplate isn't really test gear, but it'll make a great preheat/reflow hotplate. Max temperature is 450 C. It was cheap because the stirrer doesn't work. It soon will though

Talking of the current probe amplifier, if you have need to open one up then some high res pics of the internal PCBAs would be very much appreciated...(no service manual or high-res photos are available for the more modern amplifiers, and I am toying with the idea of making a DIY amplifier for my older generation probes given I have 4 probes and just 1 AM503 amplifier)

Edit: also congrats on the haul, that bottom power supply (and the collection of probes) looks especially tasty!

Thanks, and that sounds like a reasonable price too based on what I've seen them go for in the past.

I'll also prod the boss at work about getting a probe/amp set from you if there are any left (we desperately need a good current probe); unfortunately there is a lot of bureaucracy involved but if I get any interest I'll send a PM. Probably a long shot though, they'll likely insist on buying new for 5x the price then the bean counters will say no because of the cost

Edit: the "new for 5x the price" number was pulled out of the air, but I've checked and it's almost exactly right based on a TCPA300 and TCP312 from the usual rip-off merchants (RS/Farnell).

Thanks. If you have Agilent scopes: have some 1147A's as well (a bit cheaper too). Also have a P6022A that does 120MHz (AC only) that is good deal cheaper but is in a somewhat worse cosmetic shape.

Yeah, you can probably get them a bit cheaper if you negotiate or are listed in the Fortune 500 list

These are not from the US, sorry. But I don't mind at all selling to the US at and and have done so often enough in the past.

As for series connectability: 2 can be put in series according to the datasheet but also according to the DS:

- For models greater than 60 VDC rated output, no point on the Positive output shall be more than ± 600 VDC above or below chassis ground.– For models greater than 60 VDC rated output, no point on the Negative output shall be more than ± 400 VDC above or below chassis ground.

Fedex just delivered this GW INSTEK PSM-2010 power supply that was listed as-is for parts because the fan speed seemed to wander and they weren’t sure what else might be seriously wrong. New these go for about $1000 but can be quite a bit less used. This dual range model outputs 8VDC/20A or 20VDC/10A and has similar features to the HP e3632A but is newer. The manual lists one of the features as: “Intelligent control fan (Vary with different output power)” so what they thought was a fault, was a feature.

The front panel and display look like new and I re-calibrated it so it is within about 1mv and I paid well under $100 for it.
